Since the ganache layer will be in the middle, can I put a cake circle between layers 2 and 3 then lift off the top two cakes? Thus essentially having two 9" two layer cakes to serve? (Just in case that doesn't make any sense: When I say layer I mean one 2" cake, torted.) Or will this just become a huge mess? If it is a bad, bad idea, then I'm open to suggestions. It is way too tall of a cake to serve as slices.
